A novel method on the basis of multi chaos theory is suggested in the
presented study. Also, the study used two different dimensions to generate S-Box to
get a strong cipher that is difficult to break. The suggested image cryptosystem
includes an identical (decryption and encryption) process, which involves a single
keystream generator, shifting process (based on 3D Lorenz map) related diffusion
operations, and generate S-Box (based on 2D Henon map) that related confusion
operation. The comparative analysis and the simulate test show that the suggested
image cryptosystem has a few properties, like high-sensitivity, fast
encryption/decryption, large keyspace, excellent statistical properties related to the
ciphertext, and so on. The suggested cryptosystem is considered as an alternative for
practical secure communications. |
